GP-C4004 serial port server is RS232/485 developed by our company based on independent software. An isolated serial port server,It completes the overall solution of transparent transmission from 4-way serial port to Ethernet. Users can use the built-in VEE service of the device. The device can view its status, match parameters and upgrade the software, so as to improve the user's control and management ability of the device. 4-way serial port type supports desktop installation, which is convenient for some desktop installation conditions. This device serial port supports RS232/RS485 combined together. Achieve a speed of 300bps "115200bps, and the ports have height insulation, anti-static and anti-surge devices which increases the safety and stability of the equipment.

  1. Serial port RS232/RS485 two-in-one, speed 300bps-115200bps

  2. Set as TCP Client, TCp Serva, UDP, target guard and port.

  3. Communicate with the virtual serial port software developed by Socket.

  4. Supports 10M/100M, full/half duplex adaptive and cross-through adaptive
